Definitely should, the sword is awesome.l THat being said, Vampire Nocturnus is not seeing a lot of play, and will rotate out of Standard in October, so I guess the trade went fine, you got some cool cards for the upcoming season, as well as some value, like Doom Blade, Skinrender and the 2 Bonehoards. I don't think you actually did get ripped off, though Nocturnus is a mythic if I remember correctly, and, as such, less printed, so it might get harder to find one a few years from now. That being said, he won't be played outside of Standard anyway, and a singleton won't do a lot for a deck. Casual decks aside, I'd much rather have a singleton Loxodon Warhammer and Pentavus.
